Chapman is giving a mini-concert at Cash’s “One Nation Under God Rally” on Monday at the TD Center in Greenville. Cash will also give a speech about how America’s greatness came through Christian values and how the country’s place in the world is threatened in modern society.

Cash’s campaign is selling tickets for the 6: 45 p.m. event for $32. They are trying to raise money to help Cash beat U.S. Sen. Lindsey Graham, who had more than $7 million in his campaign account at the end of last year. Cash had about $250,000.

Cash is one of six Republicans trying to beat Graham in the June 10 primary.
